Now that's some quality sports journalism (or maybe I'm just relieved, having read the headline, that I didn't have to roll up my sleeves and get stuck into another argument about global warming - someone should do a study to see what impact the amount of hot air talked about global warming has had on global warming - but it wasn't that, so I'll shut up now). Thanks for the link, lawn_wrangler.

The league has to do something about all that water vapor from the steaming heads getting into the atmosphere. All that excess water vapor in the air will cause more precipitation near football stadiums. This will then have an effect on the turf, causing poor playing conditions. This is readily apparent in northern areas like Pittsburgh (this season) and New England (last season), when the fields there were nearly unplayable due to rain and snow. Obviously, global warming is caused by the NFL trying to get rid of steaming black-guy heads. Doesn't Al Gore know this?
